I have been a bit concerned about lack of accuracy and high ES numbers.
Today I decided to do setback tests with three different headstamps (WIN, Federal, Starline) and RMR FMJ and Berrys's plated bullets. I am not going to list the measurements, but basically there were zero setback after cycling the dummy rounds through the LCP twice, and pushing each dummy round down on my bench.
After the test I used my RCBS kinetic puller to pull the bullets, and this is where I can feel that there is possibly lower neck tension. This is obviously all feel, but all bullets came out on the easy side. The way I pull them is normally two light taps, and then a light hit. Second round would be two light taps and a heavier hit. All of them came out in the second round, before or with the last hit. The only way I will remedy this is with a heavier crimp or maybe seating it deeper. I am just not sure if it is worth it.
With my load research I found this article. It shows a few loads and the results. Based on these results it seems that my higher ES numbers and groupings I see, are basically in line with other LCP testing. maybe I should not be that concerned about it.
